As an experienced player and someone with a pretty strong grasp of SM’s mechanics, this is one of the most fun hacks that I’ve ever played. Each room is a puzzle that requires outside-the-box thinking and/or a fairly high-level of both understanding and executing mechanics that wouldn’t normally be used in a playthrough or speedrun. It’s full of challenging and highly rewarding puzzles accompanied by a remixed soundtrack that enhances the feeling of experiencing something new.. If you’re well-versed in the game, this hack lets you utilize some of the deeper knowledge you’ve acquired along the way. If you’re a beginner, Containment Chamber is a great opportunity to explore some of the depth that SM has to offer that would otherwise be strictly novel in its nature. Either way, I would absolutely recommend this hack to anyone who has done any speedrunning or played around with some of the more advanced tech. Truly one of the best. 9.5/10
